AI Technical Summary

Benefits of technology

The technical effect of this new type of material that can improve its properties by forming tiny layers or creating voids within it when mixed into cementitious materials like mortars without causing excessive shrinking during curing. This results in improved durability for these products while maintain their ability to absorb liquids effectively.

Problems solved by technology

This patented describes different ways to make stronger concrete structures without losing much more than needed during conventional methods like casting or molding. One way involves increasing the mixing speed of aggregates within the structure while maintaining sufficient contact area between them. Another approach focus on improving the compression properties of these aggregate mixtures. Additionally, there may also involve incorporated weak agents (water absorbents) to help reinforce the hardened concrete. These techniques aimed towards enhancing the mechanical property of concrete when mixed properly could contribute significantly to improved quality control over existing constructions.

Embodiment 1

[0046] This embodiment provides a water-permeable concrete strength agent. The raw materials of the strength agent include: 10 parts of sodium lignosulfonate, 1 part of isopentenol polyoxyethylene ether TPEG-2400, water-reducing 5 parts of medicine, 30 parts of water.

[0047] The preparation method of the water reducing agent is:

[0048] Stir and mix 20 parts of sodium lignosulfonate, 40 parts of water and 15 parts of sodium dodecyl sulfonate at 200 rpm for 90 minutes, then add 12 parts of stearyl alcohol and continue stirring and mixing at 200 rpm for 90 minutes. Stand still for 180min, and cool to room temperature to obtain the water reducer.

Abstract

The invention provides a water-permeable concrete synergist. The synergist is characterized by being prepared from, by weight, 10-25 parts of sodium lignosulfonate, 1-5 parts of allylic alcohol polyoxyethylene ether and 5-10 parts of a water reducing agent, wherein the water reducing agent is prepared from lignosulfonate, alkyl sodium sulfonate and long carbon chain alkyl alcohol. The special water reducing agent is added into the concrete synergist, the water reduction rate of the concrete is increased to 20% or above on the condition that other water reducing agents are not added while the mechanical properties of the concrete are guaranteed, and the good water permeable performance is give to the concrete.
